Pyogenic liver abscess: Klebsiella as an emerging pathogen.

Patients with pyogenic liver abscesses often present to the emergency department with fever of unknown origin. After the appropriate clinical evaluation, cross-sectional imaging may be performed in the emergent setting to aid in localization of fever source. On computed tomography imaging, pyogenic liver abscesses may present as inflammatory masses in the liver, with Escherichia coli as the most common pathogen. We report an emerging hepatic pathogen as the cause, Klebsiella pneumoniae.

CT-guided percutaneous aspiration and catheter drainage of pyogenic liver abscesses.

Surgical drainage has been the accepted method of treatment for pyogenic liver abscesses. Modern imaging techniques have revolutionized the diagnosis and management of liver abscesses. Percutaneous aspiration and drainage have been reported as a treatment modality of pyogenic liver abscesses in the literature before. We treated 15 patients with pyogenic liver abscesses by percutaneous aspiration and drainage. All patients responded except two. No mortality was observed. Review of the literature and our experience with 15 patients suggest that because of the high recovery rate and few complications percutaneous aspiration and drainage should be the first line of treatment in the management of pyogenic liver abscesses.

Pyogenic liver abscess caused by Burkholderia pseudomallei in Taiwan.

Pyogenic liver abscess in Taiwan is a well-known disease entity, commonly associated with a single pathogen, Klebsiella pneumoniae. Melioidosis is an endemic disease in Taiwan that can manifest as multiple abscesses in sites including the liver. We report three cases of liver abscesses caused by Burkholderia pseudomallei. The first patient was a 54-year-old diabetic woman, who presented with liver abscess and a left subphrenic abscess resulting from a ruptured splenic abscess, co-infected with K. pneumoniae and B. pseudomallei. The second patient, a 58-year-old diabetic man, developed bacteremic pneumonia over the left lower lung due to B. pseudomallei with acute respiratory distress syndrome, and relapsed 5 months later with bacteremic abscesses of the liver, spleen, prostate and osteomyelitis, due to lack of compliance with prescribed antibiotic therapy. The third patient was a 61-year-old diabetic man with a history of travel to Thailand, who presented with jaundice and fever of unknown origin. Liver and splenic abscesses due to B. pseudomallei were diagnosed. A high clinical alertness to patients' travel history, underlying diseases, and the presence of concomitant splenic abscess is essential to early detection of the great mimicker, melioidosis. The treatment of choice is intravenous ceftazidime for at least 14 days or more. An adequate duration of maintenance oral therapy, with amoxicillin-clavulanate or trimethoprim-sulfamethoxazole for 12-20 weeks, is necessary to prevent relapse. Liver abscess in Taiwan is most commonly due to K. pneumoniae, but clinicians should keep in mind that this may be a presenting feature of melioidosis.

Ultrasonic features of pyogenic liver abscesses.

Ultrasonic features of 21 surgically confirmed pyogenic liver abscesses in 18 patients were analyzed. Typical lesions were round or ovoid with a discrete, irregular, echo-poor margin. The number and intensity of internal echoes and sound transmission were variable. Such lesions can be aspirated percutaneously for definitive preoperative diagnosis. Pyogenic liver abscesses appear to have more ragged walls and are less frequently elliptical or multilocular than abscesses elsewhere in the abdomen.

Pyogenic liver abscess in patients with schistosomiasis mansoni.

Schistosomiasis mansoni has been described as a predisposing factor for pyogenic liver abscess formation. Previous experimental studies have shown that acute schistosomiasis concurrent with Staphylococcus aureus bacteremia favors the colonization of the liver by the bacteria, and subsequent pyogenic liver abscess formation. In addition, clinical studies and case reports have demonstrated the association of schistosomiasis mansoni with pyogenic liver abscesses. We describe a Brazilian patient with chronic schistosomiasis mansoni who developed recurrent pyogenic liver abscesses due to Pseudomonas aeruginosa. The authors review the clinical, diagnostic and treatment aspects of patients with schistosomiasis and pyogenic liver abscess reported in the medical literature.

A "fishy" cough: hepatobronchial fistula due to a pyogenic liver abscess.

A hepatobronchial fistula is an anatomic communication between the liver parenchyma and the bronchial tree. Major causes of such fistulae include inflammatory conditions resulting from obstruction of the biliary tract and infectious processes, such as pyogenic liver abscesses, amoebiasis, and hydatid cysts. We report a rare case of a patient (with a chronic, recurrent hepatic abscess) who suffered a persistent, productive cough resulting from a hepatobronchial fistula.

Ascending cholangitis as a cause of pyogenic liver abscesses complicated by a gastric submucosal abscess and fistula.

Ruptures of nonamebic (pyogenic) liver abscesses into the thorax and peritoneum are very uncommon; but, hepatoduodenal and hepatocolonic fistulas are ever more rare. We report a case where ascending cholangitis was associated with pyogenic liver abscess formation and a gastric fistula. Drainage into the stomach was demonstrated by gastroduodenal endoscopy for gastric bleeding. After fistula formation, we could successfully treat the inflammation caused by infection of Citrobacter freundii and Candida albicans with intravenous infusion of both antibiotic and antifungal agents.

[Pyogenic liver abscesses in cancer patients].

OBJECTIVE: To analyse the clinical behaviour of pyogenic liver abscesses among cancer patients, and to determine whether there is any difference between clinical behaviour among patients without malignancies. PATIENTS AND METHODS: Retrospective, multicentric study with 133 patients with pyogenic liver abscesses diagnosed during 13 years. Patients were divided into two groups: 29 patients with malignant tumors identified during the five years prior to abscess development (group 1) and 104 patients without malignant tumors (group 2). Clinical, biological and bacteriological findings, morphology and lesional topography, treatment and particularly, clinical course were analysed. RESULTS: Abscesses with portal pathogenesis were more common in group 1 (24% versus 10%; p = 0.03). Clinical and biological data were similar in both group but jaundice (31% versus 18%; p = 0.09), liver enlargement (38% versus 21%; p = 0.06) and pleural effusion (48% versus 28%; p = 0.03), which were more common in group 1. In the same group, the mean AST level was also higher (112 149 versus 60 88; p = 0.07 ). Morphology and lesional topography, as well as bacteriology in both groups did not differ significantly. In group 1, surgical drainage was performed less frequently (21% versus 38%; p = 0.09) and mortality rate was higher (24% versus 11%; p = 0.08). Nevertheless, no significant differences were observed between hospital stay and morbidity. Among patients treated with antibiotics only, the mortality rate was higher in group 1 (50% versus 10%; p = 0.06). CONCLUSIONS: In pyogenic liver abscess in patients with malignant tumor disease a predominance of portal pathogenesis was observed. The presence of cancer among patients with pyogenic liver abscesses did not imply a significantly different clinical presentation; however, the clinical course was worse than that observed in cases without cancer.

Pyogenic liver abscess in Taiwan: emphasis on gas-forming liver abscess in diabetics.

Ninety-seven cases of pyogenic liver abscesses in a 4-yr period were studied: 27.8% (27 cases) were associated with biliary tract stone, 5.2% (five cases) were associated with biliary tract cancer, and there were two cases of diabetes (2.1%) associated with anal infection, but 63.9% (63 cases) were diagnosed as cryptogenic. Forty patients (64.5%) in the cryptogenic group had diabetes mellitus, and 23 of them (23/40, 57.5%) had gas-forming infection. All patients received parenteral antibiotics therapy, percutaneous aspiration, drainage, or operation. The overall mortality was 16.5%. Diabetes mellitus alone, without demonstrable infectious foci, was an important predisposing factor for pyogenic liver infection. Furthermore, to evaluate the clinical importance of gas-forming pyogenic liver infections, we separated these 42 diabetic patients into gas-forming and non-gas-forming groups, after sonography and CT scan. Klebsiella pneumoniae was the major pathogen in both groups. There was no significant difference in the clinical manifestations, complication, bacterial culture, or laboratory data between these two groups, except that the AST level was higher in the gas-forming group. However, the gas-forming group had higher mortality rate (30.4% vs. 5.3%). Gas-forming liver abscesses were common among the diabetics. Early and adequate drainage for pyogenic liver abscesses with parenteral antibiotics are crucial in their management.

Gas-containing pyogenic liver abscess--a case report and review of the literature.

The incidence of gas-containing pyogenic liver abscess is exceedingly rare. We report herein, a case of a 36-year-old Japanese woman with a gas-containing pyogenic liver abscess associated with diabetes mellitus and cholelithiasis. An abdominal plain X-ray film, which showed a fine air-fluid level in the liver at an up-right position, enabled us to easily diagnosed a gas-containing liver abscess. Echo-guide percutaneous drainage revealed the organism to be Escherichia coli, however, although this treatment has recently been employed often in the treatment of pyogenic liver abscesses, especially single abscesses, it did not prove effective in this case. We finally cured the gas-containing pyogenic liver abscess by operative drainage.

[Septic shock associated with pyogenic liver abscess rescued with percutaneous transhepatic abscess drainage].

We report a case of septic shock associated with pyogenic liver abscess rescued with percutaneous transhepatic abscess drainage (PTAD). A 70-year-old male patient was admitted to our outpatient department of internal medicine with general fatigue, dullness of bilateral shoulders and extremities, appetite loss, weight loss, headache, and vertigo. Laboratory tests showed severe inflammatory indications, anemia, and high values of hepatobiliary enzymes and blood sugar. Abdominal ultrasonography and enhanced CT showed a pyogenic liver abscess of 10 cm in diameter at S 6-7 in the right hepatic lobe. The patient's condition deteriorated suddenly that night. From the results of abdominal ultrasonography and enhanced CT, we made diagnosis of septic shock associated with pyogenic liver abscess. Emergency abdominal ultrasound-guided PTAD was performed under local anesthetic. Postoperatively, the antibiotic was infused daily through a PTAD tube into the liver abscess space. He recovered and his laboratory tests improved gradually. On abdominal ultrasonography and enhanced CT, the liver abscess disappeared by 19th postoperative day, and PTAD tube was removed. There was no complication during PTAD treatment. We conclude that patients in septic shock should undergo further examinations immediately and treatment of the infected tissue should be started as soon as possible. PTAD may be an additional effective procedure for pyogenic liver abscess in septic shock. Furthermore, local antibiotic lavage through a PTAD tube into the liver abscess space may be an important supplementary method in the management of the illness.

Pyogenic liver abscess: is drainage always possible?

The treatment of pyogenic liver abscess generally involves antibiotic therapy and radiological percutaneous drainage or aspiration. Surgical drainage is rarely advisable. We report a case of multiloculated liver abscess that was not suitable for either percutaneous drainage or open surgical drainage. The only successful approach was a left hepatectomy.

Review of pyogenic liver abscess at the Royal Adelaide Hospital 1980-1987.

Pyogenic liver abscess is an uncommon condition which carries substantial morbidity and mortality if untreated. A review was undertaken of 31 patients who were admitted to the Royal Adelaide Hospital (RAH) between January 1980 and December 1987 and who were diagnosed as having pyogenic liver abscess. The aims of the study were to review the aetiology, current methods of investigation and treatment of the disease, and to formulate a management plan based on the findings. Hypoalbuminaemia, leukocytosis and elevated alkaline phosphatase were the most common findings. Hyperbilirubinaemia was not a usual feature. Computerised tomography (CT) scanning and ultrasound were the most useful imaging modalities in identification of the abscess. The sensitivity of CT scanning in evaluating the size of abscesses was lower than anticipated and this may lead to a higher than necessary rate of surgical drainage. A case is presented to illustrate this. Most abscesses were secondary and frequently due to extension of infection from biliary structures. Diseases causing diminished resistance to bacterial infection had a significant role in the pathogenesis. The overall mortality rate was 25%. Risk factors increasing mortality included advanced age, multiplicity of abscesses, depressed immune status and the presence of complications due to the abscess. Of patients who survived, four were treated with antibiotics alone, eleven with percutaneous drainage and antibiotics, and eight with surgery and antibiotics. We conclude that patients with hepatic abscesses should be managed initially by CT or ultrasound-guided aspiration. If pus is obtained a percutaneous drain should be inserted into the cavity and systemic antibiotics administered.(ABSTRACT TRUNCATED AT 250 WORDS)

[Therapy of pyogenic liver abscess].

Between 1980 and 1986, 11 patients with pyogenic liver abscess were treated at the Department of Internal Medicine at the Kantonsspital St. Gallen. 2 patients underwent successful surgical drainage and 9 patients percutaneous needle aspiration or drainage. 7 were successfully treated while 2 required secondary surgical drainage. Our results suggest that percutaneous aspiration or drainage of pyogenic liver abscess should be tried before surgery is considered.

The clinical presentation of pyogenic liver abscess.

The high mortality rate from pyogenic liver abscess is contributed to by delay in diagnosis. The widespread availability of radio-isotope liver scanning facilitates diagnosis once a hepatic abscess is suspected. This retrospective study identifies diagnostic features present at the time of admission to hospital in 28 patients who were subsequently found to have a hepatic abscess.

Pyogenic liver abscess.

Experience with 34 patients with pyogenic liver abscess is reviewed to evaluate the impact of percutaneous drainage and duration of antibiotic therapy on results of treatment. Patients with shock, adult respiratory distress syndrome, disseminated intravascular coagulation, jaundice, severe hypoalbuminemia, and diabetes had a poor prognosis. Percutaneous drainage was used successfully in 4 of 6 patients, but its use did not affect mortality rate or length of hospital stay. Percutaneous drainage may be the procedure of choice for selected patients. Half of our patients received antibiotics for 2 weeks or less with no abscess recurrences in this group. Long-term antibiotics may not be necessary after adequate surgical or percutaneous abscess drainage.
